lcfirst
lcfirst(string)
Returns string with the first character converted to lowercase.
Examples
-
Convert the first character of a string to lowercase:
julia> lcfirst("Hello") "hello"This example converts the first character of the string "Hello" to lowercase.
-
Handle an empty string:
julia> lcfirst("") ""When the input string is empty, the function returns an empty string without any changes.
- Preserve the case of subsequent characters:
julia> lcfirst("JuliaLang") "juliaLang"The function only converts the first character to lowercase while preserving the case of subsequent characters.
Common mistake example:
julia> lcfirst(123)
ERROR: MethodError: no method matching lcfirst(::Int64)In this example, the input type is incorrect. The lcfirst function expects a string as input. Make sure to pass a valid string argument to avoid such errors.
